LED solar street light heat dissipation

Since the LED solar street light is a semiconductor component, the temperature will affect the service life of the LED solar street light, including the light decay, lamp beads, light efficiency and wiring of the LED solar street light. LED solar street lights are not only waterproof and lightning protection in harsh outdoor environments, but also very important for heat dissipation.

LED solar street light LED chip

With the rapid development of the LED industry, a large number of new manufacturers have also been attracted, but there are many technical problems, and there are also problems with the quality of the products. Some manufacturers use 1w low-power LED chips instead of 3-5w for high returns. It is easy to increase the light decay of street lamps in a short period of time. It is important to know that the use of LED street lights can reach about 50,000 hours, but if the light decay is high, the lighting efficiency will be reduced, and failures will also occur. When purchasing LED solar street lights, you must Pay attention to the power of the LED chip.

LED solar street light luminous efficiency

With the maturity of technology, luminous efficiency has become a standard for people to choose LED solar street lights. The luminous efficiency of ordinary high-pressure sodium lamps is 100LM/W, the commonly used LED street lamps are 50-60LM/W, and foreign LED chips can reach 80LM/W. The higher the luminous efficiency, the better the energy saving effect, which is also the choice of LED. One of the most important indicators of solar street lights. There are no clear rules for this in the LED specification, so pay attention when purchasing LED solar street lights.
